LYSOLAC®

LYSOLAC®: trusted to naturally protect cheese for 30 years

Cheese is susceptible to spoilage by micro-organisms, which can cause defects that dramatically reduce its quality, imparting negative odors and taste defects. LYSOLAC® has been trusted by cheesemakers for over 30 years to naturally protect the quality of cheese, maintaining its flavor and texture whilst increasing shelf-life.

LYSOLAC® is safe, easy to use, and cost-effective, taking full advantage of the natural antimicrobial properties of lysozyme. This protective enzyme is found in mothers’ milk, tears, and hens’ eggs, which powerfully disrupts the membrane of gram-positive bacteria, killing them.

When added directly to the milk, LYSOLAC® protects the cheese throughout the entire process. Its positive charge binds it to the negatively charged casein in milk, keeping LYSOLAC® active in the curd and beyond into the ripening stages. This is critical for preventing late-blowing, cracking, and splitting defects caused by Clostridium tyrobutyricum spores. These spores are notoriously resistant to pasteurization, bactofugation, and microfiltration approaches. They endure these unharmed, poised to grow weeks later during ripening when favorable conditions are favorable. Cheese protected with LYSOLAC® rapidly destroys Clostridium tyrobutyricum spores that begin to grow during ripening, entirely preventing late-blowing spoilage of cheese.

Bioseutica® LYSOLAC® - LAB Bacterial Inhibition

LYSOLAC® Inhibits growth of Clostridium tyrobutyricum

LYSOLAC® is active against Clostridium tyrobutyricum vegetative cells in the milk. LYSOLAC® (positively charged at milk pH) electrostatically attracts to the casein (negatively charged) and is retained in the cheese curd. The LYSOLAC® bond remains active in the curd and duration of the cheese aging processes against Clostridium tyrobutyricum.

Interaction between LYSOLAC® added and the casein in the milk

LYSOLAC® is effective by addition in the milk, LYSOLAC® (positively charged at milk pH) electrostatically attracts to the casein (negatively charged) and is retained in the cheese curd. LYSOLAC® remains active in the curd and during the cheese aging processes.
Bioseutica® LYSOLAC® - Successful Track Record Of Over 30 Years

LYSOLAC® successful track record of over 30 years

LYSOLAC® is trusted worldwide to protect hard, semi-hard, and soft cheeses including Grano Padano DOP, Edam, Gouda, Manchego, Cheddar, Brie, Camembert, Emmentaler, Conte, Montasio, Mimolette, Provolone and Romano among others. 99% of Grano Padano DOP produced today uses the protective properties of lysozyme, with over 85% of the French hard cheese industry doing the same.

LYSOLAC® is invaluable insurance for cheesemakers, costing only 0.04€ per kilo of the finished cheese. 500 g of LYSOLAC® is enough to treat 1.65 Kilolitres of milk, providing cheesemakers with real tangible value. Available in either granulated or liquid forms, LYSOLAC® is stable for up to 3 years when kept dry at ambient temperatures.
